In an attempt to address global changes in climate, the Obama administration plans to use the Clean Air Act to limit greenhouse gas emissions from power plants. The first set of proposed Environmental Protection Agency (EPA) regulations -- aimed at reducing power plants' carbon emissions -- is due by Sept. 20.

In a live webcast conversation at 1:30 p.m. Monday, Sept. 16, three Duke scholars will preview the legal, political, environmental and economic implications of the proposed regulations.

Watch the "Office Hours" conversation live on Duke's YouTube channel. To pose a question to the participants, post it on Twitter with the hashtag #dukelive or email it to live@duke.edu.

Participating in the conversation will be Jonas Monast, director of the Climate and Energy Program at Duke's Nicholas Institute for Environmental Policy Solutions; Robert Brenner a senior fellow at the Nicholas Institute; and Jonathan Wiener, the William R. and Thomas L. Perkins Professor of Law at Duke Law School.

In announcing this summer his intention to use the Clean Air Act to limit greenhouse gas emissions, President Obama said, "For the sake of our children, and the health and safety of all Americans, I'm directing the Environmental Protection Agency to put an end to the limitless dumping of carbon pollution from our power plants, and complete new pollution standards for both new and existing power plants."

The Duke researchers will comment on what to look for in the EPA's upcoming proposal, what the regulations could mean for long-term climate policy and what technological innovations might affect climate change.

"Office Hours" is a live webcast series for the university community and others to engage with Duke scholars and their research. Watch archived episodes on YouTube or iTunes.
